Abstract
Matrix metalloproteinases (MMPs) are involved in extracellular matrix remodeling through the degradation of extracellular matrix components and are also involved in the inflammatory response by regulating the pro-inflammatory cytokines TNF-α and IL-1β. Dysregulation in the inflammatory response and changes in the extracellular matrix by MMPs are related to the development of various diseases including lung and cardiovascular diseases. Therefore, numerous studies have been conducted to understand the role of MMPs in disease pathogenesis. MMPs are involved in the pathogenesis of infectious diseases through a dysregulation of the activity and expression of MMPs. In this review, we discuss the role of MMPs in infectious diseases and inflammatory responses. Furthermore, we present the potential of MMPs as therapeutic targets in infectious diseases.

Abstract
Adult T-cell leukemia/lymphoma (ATLL) is virus-caused cancer that originates from the infection by human T-cell leukemia virus type 1. ATLL dysregulates various biological pathways related to the viral infection and cancer progression through the dysexpression of miRNAs and mRNAs. In this study, the potential regulatory subnetworks were constructed aiming to shed light on the pathogenesis mechanism of ATLL. For this purpose, two mRNA and one miRNA expression datasets were firstly downloaded from the GEO database. Next, the differentially expressed genes and miRNAs (DEGs and DE-miRNAs, respectively), as well as differentially co-expressed gene pairs (DCGs), were determined. Afterward, common DEGs and DCGs targeted by experimentally validated DE-miRNAs were explored. The oncogenic and anti-oncogenic miRNA-mRNA regulatory subnetworks were then generated. The expression levels of four genes and two miRNAs were examined in the blood samples by qRT-PCR. The members of three oncogenic/anti-oncogenic subnetworks were generally enriched in immune, virus, and cancer-related pathways. Among them, FZD6, THBS4, SIRT1, CPNE3, miR-142-3p, and miR-451a were further validated by real-time PCR. The significant up-regulation of FZD6, THBS4, and miR-451a as well as down-regulation of CPNE3, SIRT1, and miR-142-3p were found in ATLL samples than normal samples. The identified oncogenic/anti-oncogenic subnetworks are pieces of the pathogenesis puzzle of ATLL. The ultimate winner is probably an oncogenic network that determines the final fate of the disease. The identified genes and miRNAs are proposed as novel prognostic biomarkers for ATLL.

Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) can be curative for adult T-cell leukemia/lymphoma (ATL), but comorbidities increase transplant-related mortality. Here we report the outcome of allo-HSCT in a patient with ATL with human T-cell leukemia virus type I (HTLV-1)-associated myelopathy-tropical spastic paraparesis (HAM/TSP). A 48-year-old man was diagnosed with HAM/TSP and started prednisolone therapy. Ten years later, he developed lymphoma-type ATL. At the diagnosis of ATL, Osame's Motor Disability Score (OMDS) was 4. When prednisolone was gradually tapered and stopped following chemotherapy for ATL, HAM/TSP symptoms recurred (OMDS 7). Bone marrow transplantation from a human leukocyte antigen allele 8/8 matched unrelated donor was performed while ATL was in partial remission. Neutrophil engraftment with complete donor chimerism was achieved on day 19 after allo-HSCT. Mild gait improvement (OMDS 5) was observed on day 30. Although ATL relapsed on day 275, progression of HAM/TSP symptoms was not observed. Furthermore, there was no clear progression of HAM/TSP symptoms after donor lymphocyte infusions. The outcome of this case suggests that ATL patients with HAM/TSP tolerate allo-HSCT and donor lymphocyte infusions.

Abstract
Human T-cell leukemia virus type 1 (HTLV-1) causes incurable adult T-cell leukemia and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Patients with HAM/TSP have increased levels of HTLV-1-infected cells compared with asymptomatic HTLV-1 carriers. However, the roles of cellular genes in HTLV-1-infected CD4+ T cells await discovery. We performed microarray analysis of CD4+ T cells from HAM/TSP patients and found that the ABL1 is an important gene in HAM/TSP. ABL1 is a known survival factor for T- and B-lymphocytes and is part of the fused gene (BCR-ABL) known to be responsible for chronic myelogenous leukemia (CML). ABL1 tyrosine kinase inhibitors (TKIs), including imatinib, nilotinib, and dasatinib, are used clinically for treating CML. To evaluate whether ABL1 is indeed important for HAM/TSP, we investigated the effect of TKIs on HTLV-1-infected cells. We developed a propidium monoazide-HTLV-1 viability quantitative PCR assay, which distinguishes DNA from live cells and dead cells. Using this method, we were able to measure the HTLV-1 proviral load (PVL) in live cells alone when peripheral blood mononuclear cells (PBMCs) from HAM/TSP cases were treated with TKIs. Treating the PBMCs with nilotinib or dasatinib induced significant reductions in PVL (21.0% and 17.5%, respectively) in live cells. Furthermore, ABL1 siRNA transfection reduced cell viability in HTLV-1-infected cell lines, but not in uninfected cell lines. A retrospective survey based on our clinical records found a rare case of HAM/TSP who also suffered from CML. The patient showed an 84.2% PVL reduction after CML treatment with imatinib. We conclude that inhibiting the ABL1 tyrosine kinase specifically reduced the PVL in PBMCs from patients with HAM/TSP, suggesting that ABL1 is an important gene for the survival of HTLV-1-infected cells and that TKIs may be potential therapeutic agents for HAM/TSP.

Abstract
Human T-lymphotropic virus type 1 (HTLV-1) is the etiologic agent of both adult T-cell leukemia/lymphoma and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is clinically characterized by chronic progressive spastic paraparesis, urinary incontinence, and mild sensory disturbance. Given its well-characterized clinical presentation and pathophysiology, which is similar to the progressive forms of multiple sclerosis (MS), HAM/TSP is an ideal system to better understand other neuroimmunological disorders such as MS. Since the discovery of HAM/TSP, large numbers of clinical, virological, molecular, and immunological studies have been published. The host-virus interaction and host immune response play an important role for the development with HAM/TSP. HTLV-1-infected circulating T-cells invade the central nervous system (CNS) and cause an immunopathogenic response against virus and possibly components of the CNS. Neural damage and subsequent degeneration can cause severe disability in patients with HAM/TSP. Little progress has been made in the discovery of objective biomarkers for grading stages and predicting progression of disease and the development of molecular targeted therapy based on the underlying pathological mechanisms. We review the recent understanding of immunopathological mechanism of HAM/TSP and discuss the unmet need for research on this disease.

Abstract
Much progress has been made in the identification of specific human gene variants that contribute to enhanced susceptibility or resistance to viral diseases. Herein we review multiple discoveries made with genome-wide or candidate gene approaches that have revealed significant insights into virus-host interactions. Genetic factors that have been identified include genes encoding virus receptors, receptor-modifying enzymes, and a wide variety of innate and adaptive immunity-related proteins. We discuss a range of pathogenic viruses, including influenza virus, respiratory syncytial virus, human immunodeficiency virus, human T cell leukemia virus, human papilloma virus, hepatitis B and C viruses, herpes simplex virus, norovirus, rotavirus, parvovirus, and Epstein-Barr virus. Understanding the genetic underpinnings that affect infectious disease outcomes should allow tailored treatment and prevention approaches in the future.

Abstract
Human T cell leukemia virus type 1 (HTLV-1) is a human retrovirus etiologically associated with adult T cell leukemia/lymphoma and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only approximately 0.25-4 % of infected individuals develop HAM/TSP; the majority of infected individuals remain lifelong asymptomatic carriers. Recent data suggest that immunological aspects of host-virus interactions might play an important role in the development and pathogenesis of HAM/TSP. This review outlines and discusses the current understanding, ongoing developments, and future perspectives of HAM/TSP research.

Abstract
Human T-cell leukemia virus type-1 (HTLV-1) is a replication-competent human retrovirus associated with two distinct types of disease only in a minority of infected individuals: the malignancy known as adult T-cell leukemia (ATL) and a chronic inflammatory central nervous system disease HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). HAM/TSP is a chronic progressive myelopathy characterized by spastic paraparesis, sphincter dysfunction, and mild sensory disturbance in the lower extremities. Although the factors that cause these different manifestations of HTLV-1 infection are not fully understood, accumulating evidence from host population genetics, viral genetics, DNA expression microarrays, and assays of lymphocyte function suggests that complex virus-host interactions and the host immune response play an important role in the pathogenesis of HAM/TSP. Especially, the efficiency of an individual's cytotoxic T-cell (CTL) response to HTLV-1 limits the HTLV-1 proviral load and the risk of HAM/TSP. This paper focuses on the recent advances in HAM/TSP research with the aim to identify the precise mechanisms of disease, in order to develop effective treatment and prevention.

Abstract
Remodeling of skeletal muscles is regulated by matrix metalloproteinases (MMPs). Functional genetic polymorphism (PM), modulating the expression of some MMPs, might be associated to different body composition and muscular strength improvement after exercise. Genetic PM of MMP-1 (G+/- at -1607), MMP-3 (5A/6A at -1171) and MMP-9 (Cytosine-Adenine microsatellite=(13-27)CA) repeats, around -90), body cell mass (BCM), extracellular water (ECW) and isometric maximal extensor strength (MES) of both legs were determined in 17 old sedentary women at the beginning and at the end of a 24 week physical exercise program. A 12 and 72% increase in BCM and MES, respectively, and 11% reduction in ECW were observed at the end of the program. Carriers of G-insertion in MMP-1, PM increased their BCM (7 kg vs. -1.5, p=0.007) and lost ECW (9% of total body water vs. 0.1%, p=0.004) more than the non-carriers; homozygote for 21 or less CA repeats/allele in MMP-9 PM gained more MES (115 N, interquartile range=IQR=63-132) than carriers of longer microsatellites (63 N, IQR=40-86, p=0.028). MMP-3 did not show any association with body composition and exercise-related strength changes. Exercise in elderly women increases BCM and strength, these changes are associate to specific MMP genotypes.

Abstract
Repetitive DNA motifs may fold into non-B DNA structures, including cruciforms/hairpins, triplexes, slipped conformations, quadruplexes, and left-handed Z-DNA, thereby representing chromosomal targets for DNA repair, recombination, and aberrant DNA synthesis leading to repeat expansion or genomic rearrangements associated with neurodegenerative and genomic disorders. Hairpins and quadruplexes also determined the relative abundances of simple sequence repeats (SSR) in vertebrate genomes, whereas strong base stacking has permitted the expansion of purine.pyrimidine-rich SSR during evolutionary time. SSR are enriched in regulatory and cancer-related gene classes, where they have been actively recruited to participate in both gene and protein functions. SSR polymorphic alleles in the population are associated with cancer susceptibility, including within genes that appear to share regulatory circuits involving reactive oxygen species.

Abstract
HTLV-1 is the etiologic agent of ATL and HAM/TSP. The majority of HTLV-1-infected individuals remain asymptomatic, indicating that the infection alone is not sufficient to cause the diseases. It has been reported that cytokine gene polymorphisms, including polymorphisms at IL-6 and IL-10 gene, might be important. We analyzed SNP in the promoter region of the IL-6: -174, -572, -597, and -634 positions, and IL-10: -592 position to evaluate the role of these polymorphisms in the HAM/TSP pathogenesis in 133 HTLV-1 infected individuals and in 100 healthy individuals from Salvador, Bahia, Brazil. The -634C allele frequencies were higher among HAM/TSP patients (21.2%) than among oligosymptomatic (6.5%; P = 0.038) and asymptomatic (9.5%; P = 0.025) subjects. Similarly, the -174G allele frequencies were higher in HAM/TSP patients than in oligosymptomatic patients (P = 0.02). Moreover, the -634GC/-174GG genotype combination was identified at a higher frequency (38.5%) in the HAM/TSP patients than in subjects with other clinical status (8.7%; P = 0.016 for oligosymptomatic and 15.5%, P = 0.012 for asymptomatic patients). However, the multivariate logistic regression including the genotypes of the three studied loci showed that only -634 C IL-6 carriers remain as significant and independent TSP/HAM predictor (odds ratio [OR] = 5.31; 95% [CI] = 1.60-17.56; P = 0.006). We suggest that -634 G C in IL-6 could contribute to HAM/TSP development and that identification of the collective influence of several cytokine polymorphisms, their prevalence, and their interaction could help to better understand this disease.

Abstract
CD8(+) T cells contribute to central nervous system inflammation in human T-cell lymphotropic virus type I (HTLV-I)-associated myelopathy/tropical spastic paraparesis (HAM/TSP). We analyzed CD8(+) T-cell dysfunction (degranulation and IFN-gamma production) and have demonstrated that CD8(+) T cells of patients with HAM/TSP (HAM/TSP patients) spontaneously degranulate and express IFN-gamma in ex vivo unstimulated culture. CD8(+) T cells of HTLV-I asymptomatic carriers and healthy donors did not. Spontaneous degranulation was detected in Tax11-19/HLA-A*201 tetramer(+) cells, but not in CMV pp65 tetramer(+) cells. Interestingly, degranulation and IFN-gamma production in CD8(+) T cells was induced by coculture with autologous CD14(+) cells, but not CD4(+) T cells, of HAM/TSP patients, which correlated with proviral DNA load in CD14(+) cells of infected patients. Moreover, the expression of IL-15, which induced degranulation and IFN-gamma production in infected patients, was enhanced on surface of CD14(+) cells in HAM/TSP patients. Blockade of MHC class I and IL-15 confirmed these results. Thus, CD8(+) T-cell dysregulation was mediated by both virus infection and enhanced IL-15 on CD14(+) cells in HAM/TSP patients. Despite lower viral expression than in CD4(+) T cells, HTLV-I-infected or -activated CD14(+) cells may be a heretofore important but under recognized reservoir particularly in HAM/TSP patients.

Abstract
There is strong evidence at the individual level and the population level that an efficient cytotoxic T lymphocyte (CTL) response to HTLV-1 limits the proviral load and the risk of associated inflammatory diseases such as HAM/TSP. This evidence comes from host population genetics, viral genetics, DNA expression microarrays and assays of lymphocyte function. However, until now there has been no satisfactory and rigorous means to define or to measure the efficiency of an antiviral CTL response. Recently, methods have been developed to quantify lymphocyte turnover rates in vivo and the efficiency of anti-HTLV-1 CTLs ex vivo. Data from these new techniques appear to substantiate the conclusion that variation between individual hosts in the rate at which a single CTL kills HTLV-1-infected lymphocytes is an important determinant, perhaps the decisive determinant, of the proviral load and the risk of HAM/TSP. With these experimental data, it is becoming possible to refine, parameterize and test mathematical models of the immune control of HTLV-1, which are a necessary part of an understanding of this complex dynamic system.

Abstract
Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes that perform multiple roles in the normal immune response to infection. MMPs facilitate leucocyte recruitment, cytokine and chemokine processing, defensin activation and matrix remodelling. However, excess MMP activity following infection may lead to immunopathology that causes host morbidity or mortality and favours pathogen dissemination or persistence. Here, we review the normal functions of MMPs in immunity and then discuss viral and bacterial infections where excess MMP activity has been implicated in pathology, specifically examining HIV, HTLV-1, hepatitis B, endotoxin shock, Helicobacter pylori and Mycobacterium tuberculosis. Tissue destruction may be exacerbated further by bacterial-derived enzymes which activate the host pro-MMPs. Finally, the potential for therapeutic targeting of excess MMP activity in infection is considered.
